Gonna play this shit on a 22".
They are smart enough to know that not everyone will be able to run at full graphics so they have to have taken in the fact that a lot of people who want to play are just people using a low stock computer. I'm sure it will be alright if you turn the graphics down. Take UT2k4 for example. At high specs even those with high end computers have a hard time running it sometimes. I think it's the same with this.
